Find (f ° g)(0). *
atroni [7]

Answer:

B

Step-by-step explanation:

Remark

I have to represent f(x) as plus +f(x)

I like to show this situation as +f(g(x)) which I think is much clearer.

+f(x) = 5x - 4    

Solution

+f(g(x)) = 5(g(x)) - 4  What has happened is that wherever you see an x on the right you put in g(x).

Now on the right, you put whatever g(x) is equal  to.

+f(g(x)) = 5(x^2 - 1)  - 4    

Remove the brackets.

+f(g(x)) = 5x^2 - 5 - 4

And make x = 0

+f(g(0)) = 5*0 - 5 - 4

+f(g(0)) = - 9

Simplify the following leaving your answer in positive index<br><br> 1) (x/y)^-4 x (y/x)^8
Basile [38]

Answer:

(\frac{x}{y})^{-4} * (\frac{y}{x})^8 = (\frac{y}{x})^{12

Step-by-step explanation:

Given

(\frac{x}{y})^{-4} * (\frac{y}{x})^8

Required

Determine the solution to this

(\frac{x}{y})^{-4} * (\frac{y}{x})^8

In law of incides:

\frac{a}{b} = \frac{b}{a}^{-1}

This implies that:

(\frac{x}{y})^{-4} * (\frac{y}{x})^8 is equivalent to:

(\frac{y}{x})^{-(-4)} * (\frac{y}{x})^8

(\frac{y}{x})^{4} * (\frac{y}{x})^8

Apply first law of indices:

(\frac{y}{x})^{4+8

(\frac{y}{x})^{12

Hence:

(\frac{x}{y})^{-4} * (\frac{y}{x})^8 = (\frac{y}{x})^{12
